OK. 2004 6M/T Baseline, bone-stock dyno was done today at Altered Atmosphere during their annual G/Z meet.

Conditions:
59 degrees, 29.6 in-Hg, 6% humidity, Uncorrected

Three pulls were done. Here are the results:

HP Torque
Run 1 240.28 236.35
Run 2 238.66 260.87 (blip in the graph)
Run 3 239.91 238.11

Needless to say, I was quite happy with these numbers.

I was running pretty lean from 4000-5000 rpm initially (~16:1). They changed the sensor to a new one and I was around 15:1 on the last run.

So, these are the base numbers I am working with.
My exhaust and JWT clutch/flywheel come in on Tuesday, so by the end of next week I should have these as well as the spacer and UR pulley set in and ready for another dyno.

Once this is all done, I will consider getting the re-flash from Altered Atmosphere to finish it off.

 

nice numbers for a bone stock

 

Thanks. I hope to put another 20-40 on it when all N/A is said and done!

 

bone stock usually run rich. if your running 16:1, kiss your motor good bye

 

i was there today too. What color was your G?

 

great numbers

 

I was a Diamond Graphite with a lip spoiler.

As for the A/F, on the second run after they replaced the probe, it came up at 15:1 which is not too far off from the 14.2:1 ideal.

Take a look at this A/F graph:

 

Do you think the lack of humidity (6%) could have had anything to do with the reading?

Nobody seemed to think there was any reason to be concerned over the ratio. They did say that their re-flash does add fuel at higher rpms.
